SD Card - Can't Get Any to Work Anymore - LG V20 Questions & Answers

V20 H918 10j (still on Nougat)
Here's when it happened:
We were going on a road trip so I shut the phone off, took out the SD card (64 gig Sandisk), then the sim card, put the SD card back in and closed up the phone. I did not turn the phone back on. Then put the sim card in my tablet so it would have data. That worked fine.
The next day, I want the sim card back in my phone, so I do the reverse. Boot up the phone and it does not see the SD card at all. I put the SD card in the tablet and the tablet sees it just fine. Back in the phone - no go. I try a couple reboots and nothing. Boot to TWRP, it doesn't see it.
I get home and dirty flash the rom (Ovrdrive). Still doesn't see the card. I try a couple other cards (32 and 64 gig sandisk) which work just fine in other devices and the computer and the phone either doesn't see the cards or it says they are corrupt. So I format a 32 gig card (I did it a couple times in both xfat and fat32), put it in the phone and the phone says it is corrupt and needs to be formatted. So I select format. The format box is immediately at 20% and then it crashes.
I tried using ES File Explorer on the phone to format it but still a no go. I re-flashed the kernel that I have been using for the last year, that didn't help either. I used contact cleaner spray and then even used a soft small paint brush to try and clean the contacts. Nothing.
I had not put any new apps or made any changes to the phone in over a month before this happened. So.... I think somehow the pins for the card somehow got damaged or just old and something just got bent or broken or tweeked. I have another V20 that got water damaged and I looked closely at the SD card pins and compared to the current phone. I can't see any difference.
I'm posting this in case anyone else has had this problem and 1. was able to resolve it or 2. replaced the sim reader and that fixed it. Sim readers on ebay are cheap, but they have to be soldered in. Something that small is beyond my skill level.
There is a thread for the G6 that talks about this same problem. No solution. Speculation about having the card reader replaced. One person did a complete factory reset twice and that didn't work. So I'm left to believe this is a hardware issue.
Cheers.

my htc tytn doesn't recognize storage card

i have delited a program from my MSD Card and from that point my PDA does not recognize my storage card, the card is recognized by my computer, i have tryed other cards and the PDA does not recognise any of them,
does any one can help me please
1st try to clean out the sd card slot in case of something in there causing trouble. Use a can of compressed air to blow out any dust or anything. The reason I said use compressed air is because just blowing can leave moisture on the contacts causing corrosion sooner or later.
Backup the sd card then reformat it FAT32, put everything back on then see what happens.
If this doesn't work, see if it registers another sd card. If it does then it could be a problem with the card, if it doesn't then you might need to HR.
If you used backup software, now would be the time to use it...
Cheers...
I agree 100000000x times with this guy. I have owned my pre-owned Hermes for about two weeks and I was about to cry because ever since I have owned it, the sd card slot never worked. I even tried multiple cards and nothing worked. I was about to give up hope Once I tried using a can of air and cleaned the slot out thoroughly, the Hermes started recognizing the cards. I'm happy as hell now
I had the same problem, I just now placed a different storage card reads it, and it is playing.
It is palying this brand: "kingston SDCO2G" 2GB.

[Q] SD Card crashed?

You guys are the most helpful!
My 16gb sandisk micro sd card is no longer being recognized. I booted my HTC HD2 in Android and mounted the sd card to transfer pics to my pc. Just then I got a call coming in and the phone immediately became unresponsive. I kept getting the force close message but I couldn't stop it (it seemed to be in a loop) So I unsafely disconnected the phone from the pc, took out the battery and rebooted it. It started up in windows, but when I went to check for the sd card it could no longer be found. I pull out the card put it back more than twice, and yet the phone failed to recognize my memory card.
Please help me guys
put the sd card into a card reader, connect to your pc and if if its recognised there, it might be a dying card I've lost 1 16GB and an 8GB in 18 months with my hd2
If the pc recognises the card with no error save the date, reformat to primary partition fat 32 using Easeus free edition, also try the phone without the card
Thank u
Hey ..I really do appreciate the time u took to respond. Funny I was thinking the same thing....I broke my old card reader, now I have to get another another on from Amazon.com. As soon as I can lay my hands on one that is gonna be my first move.
Again, thanks a bunch.
P.S
Sadly I feel like an idiot for not backing up my sd card...(more than 3000 photos on there )

After trying the SD Card thru a card reader and if it still doesn't work/recognize it - then your mobile (hd2's)windows is corrupted - coz the same happened with me thrice and ultimately I took it back to the HTC service centre and they re installed the windows 6.5 and since then everythings is working normally and there is no problem with the SD Card anymore, but your old card becomes thrash and you'll have to get a new card :0)

Same here. Lost a sd-card recently but probably due to my own fault.
The card was difficult to get out of the reader (Yup, it seems there is some tolerance on the size) so I had to use some small tweezers.
I finally managed to get it out without any visual damage but after inserting it in the HD2 it couldn't see it anymore, neither in the cardreader afterwards.
What I think is that I had physically bent the card and broke the connections to the actual memory chip.
Some good advice on memory cards and I can't stress this out enough especially for dedicated photo equipment. Instead of buying a 16GB card buy 2 x 8GB and from a known seller and known brand.
The best and probably worst experience example that I can give is from a couple who were on their honeymoon and lost all of their pictures because of a el-cheapo 8GB memorycard.
For a phone it is something else but I made a custom out of it to create a map on my c-drive called sd-card phone. Ok it is not a every week copy but it is handy to have the data on my pc and on my phone.

Blank SD Card SD card is blank or has unsupported files

I bought a generic 64GB sd card off ebay. Card worked in my phone till i tried to transfer files to it then all of a sudden after reboot it shows "Blank SD Card SD card is blank or has unsupported files" The funny thing is this card read in any other phone my wifes s3 my mothers LG and even my co workers S4 (granted shes on ATT) It does not matter how many times i take it out and put it back in I still get the blank SD. I put it in a card reader and all the files are there. I have formated it to ext4 fat32 and it came fatext and once in a while if i format it it shows up in phone again till i try to put files on it and back to blank sd. I can read and write files to it no problem in another phone and sd card reader. plug and unplug it all day and it still loads up. Except on my phone. Im thinking i have a defect on my new phone. Anyone else have this problem? I even updated to the MF9 to see if this was a bug maybe they fixed. But i think its the phone when i was rooted with TWRP even twrp would freeze if i had the card plugged in till i ejected it. Oh yea cant even format it in the phone it has the option but does not work either. Some times it just keeps telling me its safe to remove card no matter how many times I hit mount.
These are the sort of things generic cards do. Your best solution is to get an authentic sd card. Be it big name brand or small.
I had this issue on my first sgs4, it also had some issue where it wasn't reading the battery properly (always at 100%). The first 32 GB card did this,read it fine at first then the sd went and did the issue you're having. Returned the phone and the same thing happened on the new phone. The card was some off brand (pny I think). Picked up a 64GB SanDisk has been working so far, but I saw this error come up fora moment but it quickly remounted.
Kind of scared it would happen again (my alarm clock will fail if the sd card dismounted). So I had to go get an old fashioned alarm clock for the first time in7 years.

[Q] Broken MicroSD slot?

Is this a common issue with the Note 3? I was given an SM-N900 a while back and bought a 64gb microSD. One day I took it out, transferred some files onto it from my computer, and replaced it. The phone didn't detect it. I tried an old 2gb card. The phone detected it, said it needs to be formatted, I formatted it, and it says the same thing. I've tried a wide range of formats on both cards (fat32, exfat, ext2,3,and 4, ntfs) and it's always the same thing. Both cards work normally in my computers and in an Xperia Z. They won't mount in recovery either, so I'm thinking the reader must be damaged, maybe a contact bent or broken off. Has anyone else experienced this?
maybe the slot is dirty inside and contacts are not working well. you can clean the slot with toothbrush it may help
Thanks, I'll give that a try.

SIM card and MicroSD card died on my X Force :(

I got a Sandisk 64GB MicroSD card in the mail today. Inserted it. Used it as internal storage (should have set it to portable now I think about it). It was working for a while. I was recording some dash cam video in the car with it. I tried to copy the video files off over USB in MTP mode and the first file played fine. Then I tried another and it complained. Eventually it said it was corrupted. I tried to erase the card in the phone and it said it was corrupted. I took the MicroSD card out and tried it in a card reader in Windows but it was not readable and would not let me format or test it for errors. I have now put it in my laptops card reader and it initially had the same errors but I have chosen to do a full format and right now it is coming up to half way through a full format. Hopefully that will fix it. However!
Now my SIM card will not read! I have tried re-seating it. Cleaning the contacts etc. No dice!
EDIT: Factory reset did not help. Back to the shop in the morning but I bet they don't have any stock to replace it with.
The next step is a reset of the phone but I don't hold out much hope
EDIT: Tried a factory reset and it's still not seeing it. Back to the shop in the morning and I bet they don't have any in stock to replace it with.
Probably silly question, did you put SIM in the right place? Try to reset phone from recovery or fastboot, maybe even reflash firmware.
SIM card died from being taken out and put back in too many times I think. I am waiting for the replacement MicroSD. Which means going through the motions again. I had to wait all day for my replacement SIM to become activated too because my networks systems were down which was a right pain. I am going to torture test the MicroSD outside the phone this time before using it (and to test if it's genuine). I've ordered a compatible card reader as well since my old card reader does not support MicroSDXC.
So SIM slot in the phone is still fine? That's good. New MM feature to make sd card as part of internal memory is... well, good idea but taken from years ago when devs made it for first Nexus. But back then solution was unstable and looks like still is.
I've got the new card. Seems to run OK. Initially was slow writing in NTFS mode but after a quick erase in the phone it's better although still quite slow on writes for a UHS-1 card. I am using it in portable mode and will keep an eye on it. I ran H2testW on it on the PC and it passed fine. Basically I think I overpaid for a card that does not really need to be superfast. A bog standard 64Gb card would probably have sufficed.
